Title: Manufacture of spark plug, and spark plug
Inventor: ONO HIROSHI
IPC: H01T13/39
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug and a manufacturing method of the spark plug, capable of suppressing the occurrence and growth of cracks without causing large variations in the constituent distribution and coefficient of thermal expansion of a laser weld part in the electrode axial direction (the weld-bead widthwise direction) if the irradiation position of a laser beam is shifted (varied) in the electrode axial direction among individual spark plugs. SOLUTION: An alloy chip 34 having an intermediate coefficient of thermal expansion between that of a wear-resistant chip 33 and that of a welded part 32c is layered between the wear-resistant chip 33 and the welded part 32c, and a laser weld part B is formed along their outer circumferential surfaces so as to spread over the wear- resistant chip 33, the alloy chip 34, and the welded part 32c. This reduces variations to a relatively small range in the constituent distribution of a laser weld part in the electrode axial direction (the weld-bead widthwise direction) if the irradiation position of a laser beam is shifted (varied) in the electrode axial direction among individual spark plugs.  Accordingly, a change in coefficient of thermal expansion becomes relatively small near a boundary between the laser weld part and a precious metal chip or an electrode parent material, and therefore the occurrence and growth of cracks can be suppressed.

Title: Electrothermal transfer recording method
Inventor: MIMA SOICHIRO
IPC: B41J2/325
Filed: 1987-09-18
Abstract: PURPOSE:To ensure that the shape of recorded dots is scarcely varied and to record a stable high-quality image, by transferring an image onto a recording paper through heating a thermally transferable coloring material layer of an electrothermal transfer sheet comprising a conductive base as a heat generating resistor, a layer of a material showing superconductivity at or above normal temperature, and the coloring material layer. CONSTITUTION:When a superposed combination of a recording paper 5 and an electrothermal transfer sheet 4 is clamped between a platen 9 and an electrothermal head 8 and a voltage is applied between a recording electrode 6 and a return circuit electrode 7, an electric current is passed through a conductive base 1 and a superconductive layer 2 to generate heat, whereby a hotmelt material of a coloring material layer 3 is melted, and is transferred onto the paper 5 to form an image. When the critical temperature of a material constituting the superconductive layer is set to an appropriate value in the range of 40-100 deg.C, the temperature of the superconductive layer is raised beyond the critical temperature in the process of a temperature rise by heat generation, whereby the material constituting the layer is changed into a high resistance material. At this instant, the electric resistance of the superconductive layer is increased rapidly to, for example, about 10<13>OMEGAcm, and a large quantity of heat is generated by the inertia of the current having been flowing in the superconductive layer 2. The heat generation is finished in a short time, but the heat generated is transmitted through the coloring material layer 3, whereby the layer 3 is melted and transferred.

Title: Production of optical fiber preform
Inventor: MATSUO SHOICHIRO
IPC: C03B8/04
Filed: 1992-08-12
Abstract: PURPOSE:To provide a method for efficiently carrying out the flame polishing of a rod for core before carrying out outside vapor deposition. CONSTITUTION:A burner 3 for flame polishing and burner 4 for producing glass fine particles are fixed to a base 2 in close to each other and the base is traversed along the shaft of a rod 1 for core. Both of the burner 3 for flame polishing and the burner 4 for producing glass fine particles are used in order to carry out flame polishing of the rod. At this time, a raw material gas for glass production is not fed to the burner 4 for producing glass fine particles and only oxyhydrogen gas is fed thereto. Efficiency of the flame polishing of the rod for core is improved by jointedly using both burners. Since the feed amount of oxyhydrogen gas fed to the burner 4 for producing glass fine particles is an only amount required to produce glass and smaller than an amount fed to the burner 3 for flame polishing, heating power is not too strong and the rod is not deflected when the both burners are used.
